Extruded Rubber Expansion joint is a rubber seal for filling concrete grooves. Used for connecting with concrete or aluminum sheet Helps to support the expansion and contraction of concrete and aluminum.

Extruded Rubber Expansion joint or rubber seal to fill the concrete groove. Through the production process (Extrusion Process) that has various cross-sections such as honeycomb-like shapes and bird wings, making it popularly known as Honeycomb rubber seals, pinion rubber seals, etc.

Expansion joint rubber seal or concrete groove seal Must be rubber with good mechanical properties. Supports six stretches of concrete or aluminum, waterproof, oil and chemical resistant to the environment. And Tom has a lifespan that lasts longer than 15-25 years, so the production formula Must be a specially developed formula that passed the test Both in Ozone, Tensile Strength, Compression set, etc.
